X1 DVR playback issues

Xfinity won’t help you on these forums. Everything they are recommending doesn’t work. File a complaint with the FCC. I have done this and Comcast corporate is now engaged. The more people that do this brings awareness to the problem. Comcast has now been out to my home twice. They think this is a hardware (equipment) and/or signal (wiring) problem but it’s not. They came out replaced hardware and checked wiring replaced them still same issue. File the FCC complaint. 

I keep having the same problem periodically.  For whatever reason, the recording is corrupted.  I've called about this, and have spent hours of wasted time on the phone with techs.  It is just something they say "happens".  Resetting the whole system is really not necessary, unless you keep having the same issue in multiple recordings in a row.  Mine are usually a one off, but usually a recording of my favorite show, and a proper recording will never be produced.  Ughhhhh  Xfinity is my only internet and cable option in my location, so I'm over a barrel.

I am having the same problems with our DVR playback (ever since we started using the "new" primary cable box from Xfinity, as our old cable box that contained a local drive for some of the DVR storage was suddenly bricked). Since adding this "new", smaller main cable box every single DVR recording has moments of pixilation followed by loss of audio/video and skipping forward from a few seconds to 10 seconds or more. And it happens multiple times during every DVR playback. If you rewind and try to watch the pixilated/skipped/mangled parts of the recording they are always there, as if watching TV during a thunderstorm and losing the signal. This happens during playback on TV as well as playback on computer. We have X1 service with Xfinity's internet and WiFi system. We have done all local troubleshooting including checking all connections, rebooting, etc., and it makes no difference. This is clearly a degradation in the service provided by Xfinity, which coincided with us being forced to get this "new" main cable box and to pay MORE for the DVR storage that we were previously getting as standard with our older, local DVR drive cable box. We have resorted to deleting content we have recorded on DVR in lieu of watching that content On Demand (which requires us to sit through commercials...perhaps that's the idea behind the degradation in Xfinity's DVR service, force viewers to use On Demand service instead of DVR).

SOLUTION. I took my box to the local Xfinity store and they swapped it out. Haven’t had the problem since. 

We did the same. Now the new one is doing the same thing. So annoying. Missing sports plays, punchlines, snd just the ugliness of the digital interruption.
